Vectored Interrupt Manager (VIM) Module
19.6 VIM Wakeup Interrupt
The wakeup interrupts are used to come out of low power mode (LPM). Any interrupt requests can be
used to wake up the device. After reset, all interrupt requests are set to wake up from LPM. However, the
VIM can mask unwanted interrupt lines for wake-up by using the WAKEENASET and WAKEENACLR
register. The value in REQENASET / REQENACLR does NOT impact the wakeup interrupt.
As shown in Figure 19-10, the WAKEENASET and WAKEENACLR registers will enable/disable an
interrupt for wake-up from low-power mode. All wake-up interrupts are “ORed” into a single signal
WAKE_INT connected to the Global Clock Module.
